County Tank Capacity Requirement Recourse
Long shot, but I thought it may be worth an ask....
About 10 years ago we bought an older home (built in '79) with an original septic system -- with a basic understanding of what we were taking on. An inspection of the existing tank and field was performed and all was deemed sound at that time.
Fast forward to a couple months ago, we begin seeing indications that our drain field was failing. It's now 47 years old, so not at all surprising. An inspection of that field then confirmed that failure a couple weeks ago. So, we begin the process of working with the county to seek our options for permitting and replacement.
In that process it is revealed that when the lot was prepared for the home, the installed tank met requirements for a 3BR home. The builder then put a 4BR home on the lot. All approved by the county, which is an apparent error on their part. When permitting for our drain field replacement, we're informed that our current tank requires full replacement or the addition of an adjoining tank as part of the job, because it was deemed insufficient in size for a 4BR home -- note that the tank is otherwise sound.
Again, all of this goes back in time to when the county approved the installation and build of a system that did not conform to the home ultimately built on that land, and perhaps the liability just transfers on to the buyer(s), but curious if there is any recourse now as the county is requiring correction for a system they previously signed off on?
